12 5. MEASURING PROCEDURE If the test pins ( 3-13, Fig. 1 ) are not installed to the probe head & packed separately, please refer the following diagram to fix the test pins into the probe. 10

13 5-1 Measurement by selecting the material group 1) Power the meter using the " Power On/Off Button " (3-4, Fig. 1). Remove the " Protection Rubber " (3-14, Fig. 1) away from the " Test Pins " (3-13, Fig. 1) 2) Select the required material group via the " Material Select Button " (3-9, Fig. 1). With reference to 4-1, table 1, select a material from group ( 1-9 ). MATERIAL * For " Chipboard " select group 9. *For general woods, please select the 1-9 group " 1 " to " 9 ". * For unknown materials, such as papers, paint etc please refer to the operation procedure 5-2. For example : If the wood is " LIME ", then select " 4 ". If the material is " CHIPBOARD ", then select " 9 " 3) It is recommended that the test pins are inserted to a minimum depth of 2 mm into the material under test. If a depth of 2 mm can not be obtained, then insert the test pins to their maximum achievable depth. Fig. 2 11

14 4) Display will show the moisture contents in " % moisture content " directly. * If the sample under test has a high moisture content it may take a few minutes to obtain a stable reading. * For a moisture content ( > 30% ) the display will show " ". For a moisture content ( < 9% ) the display will show " ". 5-2 Measurement by reference method For material not in the groups ( 1-9 ), the moisture meter may be used for reference by following the procedure below : 1) Turn unit on ( Power Button ). 2) Select the material group to " 1 ". 3) Insert the test pins into the materail under test. 4) The display will show the reference moisture content in %. Consideration : This value is only for reference. Although the measured data is for reference only, it can be used to estimated the dampness of tested sample. It is a useful tool for checking the reference moisture content of material types not included in table 1. 12

15 5-3 Temp. compensation adjusting The Moisture Meter defaults to calibration for wood at 20 蚓 /68 蚌. The meter reading can be corrected approximately by adding 0.5 % for every 5 蚓 below 20 蚓. Or by subtracting 0.5 % for every 5 蚓 above 20 蚓. If the environment temperature is not 20 蚓 and a precise measurement is required, the following procedure should be followed LCD Display TEMP. ADJ. Press either TEMP ADJ Button to display 20 蚓. The temperature can be increased or decreased in 1 蚓 steps by subsequent use the relevant TEMP ADJ Button. When the required temperature value is reached the display will return to normal mode after 4 seconds non use. 13

16 Consideration : When the unit is turned off, the new temperature setting is lost and the unit will default again to 20 蚓 on power up. 5-4 Other Functions 1) Data Hold * During measurement, pushing the " Hold Button " (3-8, Fig. 1) will hold the display values & the LCD will show the " D.H " symbol. * To cancel the Data Hold function, Press the Data Hold Button, once more. 2) Data Record( Max., Min. reading) * The DATA RECORD function displays the maximum and minimum readings. To start the DATA RECORD function, press the " Record Button " (3-5, Fig. 1) once. "REC" marker will appear on the LCD display. * With the " REC " symbol indicated on the display (a) Push the " RECALL Button " (3-6, Fig. 1) once, then the " Max " symbol with the maximum values recorded will appear on the LCD display. (b) Push the " RECALL Button " once again, the " Min " symbol with the minimum values recorded will appear on the LCD display. (c) To de-activate the Data Record function, Press the " Record Button " once again. All associated display units will disappear from the LCD. 14

17 6. CALIBRATION Remove the " Protection Rubber " (3-14, Fig.1) away from the " Test Pins " (3-13, Fig. 1). 1) * Select the material groups to group " 1 " using the " Material Select Button " (3-9, Fig. 1). Push both Calibration Buttons ( up and down button together ) simultaneously. CALIBRATION + Push together at the same time * The display will count backwards from 5 to 1 after which the display will show " good " 5 to 1 15

18 2) * If the display shows " Err " the meter will need to be re-calibrated using the following method. 3) Select the material group " 1 " using the " Material Select Button ". Remove the battery cover using a small screwdriver or coin. Press and hold down the bottom Calibration Button. Using a screwdriver adjust VR1 until the display value reads Release the button, calibration is now complete. CALIBRATION + Only push the down button continuously.

19 7. MAINTENANCE 7-1 Replacement of Battery A low battery is indicated by " LBT " in the left corner of the display. To replace the battery remove the battery cover with a small screwdriver or coin and replace with a DC 9 V battery ( heavy duty type, 006P, MN1604/PP3 or equivalent ). 7-2 Replacement of test pins To replace test pins on the probe, first loosen the lock nut at the base of the pin, slide pin out and replace with new. Lock Nut Fig. 4 17

20 8. RS232 PC INTERFACE The instrument features an RS232 output via 3.5 mm Terminal ( 3-1, Fig. 1). The connector output is a 16 digit data stream which can be utilized to the user's specific application. An RS232 lead with the following connection will be required to link the instrument with the PC serial input. Meter PC (3.5 mm jack plug) (9W 'D" Connector) Center Pin... Pin 2 Ground/shield...Pin 5 The 16 digit data stream will be displayed in the following format : D15 D14 D13 D12 D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0 Each digit indicates the following status : D0 D1 to D4 D5 to D8 D9 D10 End Word Upper Display reading, D1=LSD, D4=MSD Lower Display reading, D5=LSD, D8=MSD Decimal Point(DP) for Upper display. 0 = No DP, 1= 1 DP, 2 = 2 DP, 3 = 3 DP Decimal Point (DP) for lower display 0 = No DP, 1= 1 DP, 2 = 2 DP, 3 = 3 DP 18
